“…The TEM images showed that the spherical shapes of the PDMS microgel particles prepared from FRP and RAFT polymerization are expected with a diameter of 211 and 187 nm, both of which are smaller than the DLS result (Figure c,d). The hydrodynamic diameter measured by DLS does not accurately reflect the true size of the NPs especially for soft NPs which deform their shape under external stress …”

On the basis of the continuous flow system, the residence time of the miniemulsion in the flow tube was supposed to have great influence on the crosslinking degree of PDMS microgel particles.…”

“…The crosslinking degree of PDMS microgel particles was determined using gel fraction measurement via dissolution in THF . After immersing the PDMS microgel particles in THF for 24 h, the unreacted MA-PDMS was removed by centrifugation, and then the gel content was measured by the gravimetric method with the samples dried at 60 °C for 12 h. The gel content was defined as the gel fraction (in %) that was calculated according to the relationship ( W 1 / W 0 ) × 100, in which W 0 is the primary weight of PDMS microgel particles and W 1 is the weight of the same PDMS microgel particles after THF extraction and drying.…”

As one of the most widely used silicone polymers, polydimethylsiloxane (PDMS) microgel particles have broad application prospects in the fields of sensors, polymer toughening agents, bioengineering, and drug delivery. Here, we reported the continuous preparation of homogeneous crosslinked PDMS microgel particles through photoinduced reversible addition-fragmentation chain transfer (photoRAFT) polymerization. Based on the design of methacrylate-functionalized PDMS, the introduction of photoRAFT polymerization allows the formation of microgel particles with homogeneous networks, which were more regular and have better swelling behavior than networks prepared by conventional free radical polymerization processes. Moreover, the dormant polymer chain could be reactivated and lead to the postmodification of PDMS microgel particles. The crosslinking RAFT polymerization was continuously carried out in a flow photoreactor. Uniform PDMS microgel particles with high colloidal stability could be achieved in a short time (0.5–10 min), and the crosslinking densities can be easily tuned by changing the residence time which has less effect on the final particle size.

Obtaining new silicone self-adhesive in the presence of modified illite has been described. The filler was modified with N,N,4-trimethylaniline. The effect of illite content and modification on functional properties (adhesion, cohesion, stickiness, and shrinkage) was determined. Additionally, the thermal resistance (the SAFT test) of obtained silicone pressure-sensitive adhesives was evaluated. For all the systems tested, an increase in thermal resistance and shrinkage decrease were noted. Moreover, only a slight adhesion and tack decrease was revealed. Such self-adhesives could be applied for joining elements operating at increased temperatures, e.g., in heavy industry.
